@CarloK I am having the same issues described here with a UM3E. Both nozzles press into the build plate glass when printing after active leveling. No issues printing after manual leveling. I had active leveling set to occur weekly, but in all failure cases I had triggered active leveling from the menu after changing things on the printer (print cores, build plate, etc). I am using the latest 5.2.xx firmware current as of 10 January 2020. I have tried one print with active leveling set to "always" following a manual leveling per @bsaygan's post above. I observed the printer execute the active level procedure prior to printing and it worked perfectly. More runs are needed to confirm this result is consistent.
